Thanks both, very kind of you.
Miriam, would it be something you'd share with neighbours and friends like Herr Goldmann apparently sending Passover cake to Joey every year?
Not really. There is no reason why not, but I have never heard of it being done. Matzah is purely a combination of flour and water, mixed, rolled very thin and flat, and then baked, all in less than eighteen minutes. No other ingredients are allowed, so the final product is crispy but often has a rather monotonous taste and texture, and is tedious to eat.
It replaces normal (leavened) bread during the eight days of Passover, and everyone just goes out and buys an adequate amount for their family before the beginning of Passover. The only time I have ever heard of it being shared is when one family underestimates how much they will need, and borrows some of the surplus from a neighbour.
Joey would have seen it as an unusual delicacy, and would probably have enjoyed eating a small amount of an unusual food, but by the end of eight days, you are normally very happy to get back to eating normal bread again. I've wondered if Herr Goldman sent Joey matzah as a way of disposing of his surplus!
